🤖 CHATBOT
Have you ever visited a website and a small box popped up saying, “Hi! How can I help you today?” That friendly little box is called a chatbot—a smart computer program that can chat with you just like a real person.
🧠 What Exactly Is a Chatbot?
A chatbot is a type of software designed to talk to humans using text or voice. It can answer your questions, help you solve problems, or simply chat with you for fun! The word "chatbot" comes from "chat" (talk) and "bot" (short for robot).
🛠️ How Does It Work?
Some chatbots follow rules. You click buttons or type certain words, and they reply with a set response. These are called rule-based chatbots.
Other chatbots, like ChatGPT, are powered by Artificial Intelligence (AI). These can understand natural language (just the way we speak or type) and give answers that sound more human.
